Forte Diamante is one of the top sights in Genoa for travellers who enjoy panoramic viewpoints, rugged landscapes, and stories of military strategy. Perched at 667 metres above sea level, it crowns the ridge between Val Polcevera and Val Bisagno, forming part of the city's formidable defensive system. Though the interior is no longer accessible, the fortress remains an evocative landmark, surrounded by nature and layered in history.

It is also a great place to visit on a walking tour of Genoa's hills, particularly for hikers making their way along the Forti di Genova trail. The journey to Forte Diamante, with its sweeping views over the valleys, mountains, and coastline, reveals why this stronghold was once vital to the city's protection.

History and Significance of Forte Diamante, Genoa

The site atop Monte Diamante has been associated with military activity since at least 1395, when records mentioned the “Bastia del Pino,” an early defensive position. Its strategic importance grew significantly during the Austrian siege of 1747, prompting the creation of a star-shaped palisade redoubt to protect the surrounding valleys from incoming attacks.

In 1756, the Republic of Genoa formally commissioned the construction of a major fort on the mountain, guided by Engineer Jacques De Sicre with contributions from Robert de Cotte and Marshal Antonio Federico Flobert. Despite delays caused by land disputes, the project progressed thanks to the persistence and financial support of Marquis Giacomo Filippo Durazzo. Forte Diamante was completed in 1758.

The fortress underwent multiple modifications throughout its lifetime. The original pitched slate roof was replaced with a defensive terrace during the Napoleonic period, and 19th-century enhancements by the Kingdom of Sardinia added machicolations, expanded barracks, and a semi-circular tower with a spiral staircase. The fort played a critical role in the 1800 battle between French defenders and Austrian forces led by the Count of Hohenzollern, holding firm despite a fierce siege.

By 1914, Forte Diamante was abandoned as a military site. While the structure has since deteriorated, its imposing silhouette and historic legacy endure as powerful symbols of Genoa's once extensive defensive network.
